Application filed January 28, 1927. Serial No. 163,824..

Reference is had to the accompanying drawings which illustrate the preferred form of the invention.

In said drawings:

Fig. 1 is a fragmentary-side elevation of an automobile equipped with our invention;

Fig. 2 is an enlarged horizontal sectional view taken on line 2-2 of Fig.1; I

Fig. '3 is a longitudinal sectional view taken on the line 33 of Fig. l, and having parts broken away; and

Fig. 4 is a vertical sectional view taken on line'4-l of Fig. 2.

Our invention relates to automobiles, and more particularly to a combined. automobile heater and heat regulator for the engine compartment. v

The principal object of this invention is to provide a heat regulator for the engine compartment which will permit the engine to maintain a maximum temperature so to facilitate the operationot the engine for cold weather driving, and at the same time heat the interior of the automobile.

The invention further contemplates a heat regulator for automobile engine compartskilled in the art.

ments wherein the discharge of heated air is governed, thus retaining the engine at a safe, eliticient operating temperature.

It is also an object of our invention to provide a heat regulator of this character which is constructed as a unit for installation in the side panels of the automobile hood.

The invention also provides means at the sides of the engine hood or compartment for permitting the egress of air entering the compartment through the radiator in the usual manner embodying adjustable shutters, having means tor adjusting the same whereby the engine may be retained at a predetermined temperature.

Another object of the invention resides in the provision of an automobile hood which may be opened to gain access to the engine or compartment therefor without disturbing the heat regulator or its control mechanism.

It is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the persons scope of the claims will. occur to gage eXpansible coil springs Referring to the invention as illustrated 11 1 the accompanying draw ngs. a conventional automobile 18 designated at 5, in-

cluding the hood 6 which comprises a re-" section 6 lifted, and the panels 8 swung outwardly. I

Each of the panels 8 is provided with a heat regulating device, and inasmuch'as they are identicah a description of one will sutfice for both. The heatregulating de vices each comprise a frame 11 secured to the inner face of the panelsB and formed of castings 11 connected together by bolts 12 extending through meeting ears 13% as shown in Fig. 3; the meeting edges of said castings being indicated at 14- in Fig. 1, the castings providing top, bottom and side sections. This frame 11 is arranged adja cent an opening 12 formed in the panel and is provided with a marginal flange 13 by which said frame is secured to the panel through the medium oi bolts 14% or the like.

As illustrated partly in Figs. 3 and l, the front face of the frame is formed with a rectangular head 1'5 that projects through the opening 12 and extends along the edge thereof and serves to centralize the frame.

For the purpose of controlling the egress of heated air from the hood or engine compartment and thereby control the temperature of the engine; a plurality of vertically disposed shutters 15 are mounted, within the frame 11 rearwardly of the bead 1.5 Each of these shutters ismounted on a vertical shaft 16, the upper ends ot' which are received in recesses or bearings 17 Pl'OVldGll in the upper side of the frame 11 and on. 18 accommo dated in these recesses or bearings.

The" lower ends of shafts 16 are each pivotal movement. The bearing pins 20 are firmly secured in the bottom section of the frame 11 and the rods 16 are provided with guide sleeves 19 which are pressed on to said rods and turned therewith about the pins 20 upon pivotal movement of the rods 16.

Each of the shutters 15 is fashioned from a length of sheet metal and has its rear end formed with a sleeve 21 to receive the shaft 16. To insure air tight engagement of the free ends of the shutters when the latter are in the full closed position the forward ends of the shutters are formed with semi-circular lips 22, which embrace and conform to the contour of the sleeves 21.

i i In order to shiftthe shutters simultane- A lever 27 is attached to the bar 23 and projects laterally therefrom and is provided with an upstanding flange 28, to which the forward end of the Bowden wire is attached as at 29. Cooperating with the Bowden wire 26 to'retain it in adjusted position and thereby retain the shutters in adjusted position, is a clamp 30 through which the Bowden wire passes, the former always engaging the wire with sufficient friction as to normally hold it against longitudinal move ment. The clamp 30 is formed from an outstanding arm 31 cast with the upper side of the frame 11 intermediate its ends, and is bifurcated at its outer end to provide coarting clamp jaws 32. An adjusting screw 33 is threadedly engaged with these jaws 32 whereby they may be adjusted to engage I the Bowden wire with the requisite friction;

In addition to our invention being a heat regulator for the engine compartment, it also contemplates heating the interior of the automobile. In this connection the spaces between. the chassis and sides of the engine and the rear of the engine aro'closed by walls 34%, the latter being secured to the chassis by brackets It will. be apparent that as the only exit for the heated air coming through the radiator by way of the shutters 15, thishcated air will be retained within the hood or engine compartment and. thus transmit heat within the automobile. However, only sufficient heat will be retained as to permit safe operation of the engine, and to allow some ofv the heated air to escape, the shutters will be opened to the de sired degree by manipulating the Bowden wire as above set forth.

lVhat is claimed is:

1. An automobile hood having an opening extending longitudinally thereof, a frame attached to the hood and surrounding the opening, a plurality of shutters journaled in the frame for controlling the pasdisposed bifurcated element supported by the frame, a semi-flexible operating element longitudinally adjustable through the bifurcated meinber and having operative connection with the shutters and a friction creating screw engaged with the bifurcated member to cause the bifurcated parts to frictionally engagethe operating element.

2. A. device of the kind described comprising a frame having spaced recesses in the upper wall thereof, bearing pins secured to the lower wall of the frame and alined with said recesses, pivot rods having their upper ends extended into the recesses and having their lower ends mounted for pivotal movement on the pins, guides at the lower ends of the pivot rods engaging the pins to retain said rods in pivotal contact with said pins, resilient means in the recesses for re taining the rods and guides in connected relation withthe pins, shutters mounted on the rods, and means common to said shutters for actuating them simultaneously.

3. A ventilating device of the kind describedcomprising a frame adapted to be secured to a motor vehicle engine hood adjacent an opening therein, a plurality of shutters, means for actuating said shutters, bearing pins at the lower edge of the frame, pivot rods supported on said pins and to which the shutters are connected, said frame 7 having recesses in the upper portion thereof alined with said pins and receiving the upper ends of the pivot rods, and means in said recesses engaging said upper ends of the sage of heat through the opening, a laterally rods for restraining the latter against ver- JOHN A.
